Title: Bulk material discharge mechanism from hopper - has friction plates between and upstream of toothed rollers
IPC: B65G65/42
Filed: 1974-10-24
Abstract: The mechanism is for use in the production of chipboard panels, and incorporates a belt forming the hopper floor, above which a series of parallel toothed rollers are mounted along a sloping line. In the direction of discharge (9) of the material (1) upstream of the rollers (7) are a number of friction plates (10). These are mounted between the rollers and at the same intervals, and parallel to the rollers. The plates can be combined with guide plates (12) between the hopper sidewalls so as to form a series of passages. Both sets of plates can be tilted an axes for a limited amount, these axes being horizontal for the friction plates and vertical for the guide plates.

Title: Electronic component for PCBs - has terminal wires bent back alongside component body to ge stability for reflow soldering
Inventor: WOLLENSCHLAEGER WERNER
IPC: H05K3/34
Filed: 1975-02-28
Abstract: The electronic component, for printed circuit boards, has its terminal wires back parallel to its body to provide supports for the component that allow it to be reflow soldered directly to the printed circuit board without requiring holes drilled in the board. The terminal wires are shaped so that the line through the centre of gravity of the component passes through the centre of the plane defined by the ends of the bent terminal wires, thereby giving the component sufficiently stability when seated on the printed circuit board for reflow soldering. The shape of terminal wire can be applied to all types of component.

Patent DE-2516266-A1 (DE)
Title: Feedback burner with injector fed flue gases - has wide working range to regulated air jet cross section
Inventor: KURZ GERMAN
IPC: F23C9/00
Filed: 1975-04-14
Abstract: The feedback burner uses the injector effect of the combustion for drawing flue gases back into the injector nozzle chamber. The working range of this burner is extended by the injection effect of the combustion air because the outlet cross section of the driving air jet is regulated by the air flow rate so that this cross section is reduced for decreasing the air flow rate. This outlet cross section is also regulated so that the outlet velocity of the air jet remains approximately constant over the working range of the burner. The matching is controlled by the nozzle pressure difference, by an orifice, by the fuel flow rate of by combustion air compressor speed. The regulated nozzle is readily accessible and it is situated in the cold air stream. The regulation can be carried out steplessly.

Title: Fail safe dual hydraulic system - has shut-off valves in each circuit operated by pressure difference in circuits
Inventor: DAPPER HELMUT
IPC: B60T11/32
Filed: 1975-04-23
Abstract: The dual circuit hydraulic brake system has a common pump (2) which draws fluid from a central reservoir (1) and distributes it to two circuits (4a, 4b). Each circuit is protected by a pressure control valve (10, 11) whose valve elements are held in the open position by the interaction of the pressure in each system, balanced against the pressure in the other system, and backed by an internal spring force. If any system fails then its valve automatically shuts off the supply line so that the remaining circuit is ensured a supply of fluid, and with no excess fluid leakage from the faulty circuit.

Title: Vehicle drive with optional regenerative braking - uses engine or flywheel only and engine and flywheel modes with automatic control
Inventor: BEALE JULIAN ROBERT ANTHONY
IPC: F16D43/12
Filed: 1975-07-12
Abstract: The electronically controlled vehicle drive system operates in three modes, the first with the engine only connected to the drive, the second with a flywheel only connected, and the third with both connected. Force coverters are brought into operation so that during connection and disconnection, the speed of the flywheel is maintained above a determined low level. The force is applied to the flywheel only when the speed of the engine exceeds a given low level, by means of a centrifugally actuated device, which is in turn, hydraulically operated by a fluid system. The flywheel is driven by the engine, when a reduction in speed occurs and when the ratio between the two speeds is less than 2.5 to 1.

Title: Single frequency two channel control system - uses central time base generator to allow each controller to be gated alternately
Inventor: DALLMANN HORST
IPC: G08C15/12
Filed: 1975-09-13
Abstract: Remote control of at two different objects using one high frequency radio channel without cross coupling is effected by a synchronising time base. Two separate channels are adopted for the control of two pairs of carriages. Command units issue high frequency signals within specific perids determined by local control centres. Each of these centres is coupled to a main control unit that generates time base signals over the transmission lines. The frequencies of the time base signals are different for each local control centre. Additional gating signals are derived from the time base signals that ensure that commands are generated within a specific interval.

Title: Nickel cadmium storage battery charging circuit - has series transistor in charging current path, controlled by threshold switch
Inventor: SCHWERIN RALPH
IPC: H02J7/02
Filed: 1975-10-07
Abstract: A charging circuit for nickel/cadmium batteries has a series transistor in the path of the charging current, tripped into its saturation or blocked state, depending on whether a test voltage, a function of the battery voltage and applied to the threshold switch, exceeds an upper threshold, or does not reach a lower threshold. The threshold switch (22) has a differential amplifier (25). The reference value signal (Um) and the upper threshold signal (Uv) are applied to the input of the differential amplifier. The input to the differential amplifier is an equalising signal and connected to the input is a resistor (26) a diode (27) and a transistor (28) forming a feedback path, so that when the reference signal equals or exceeds the upper threshold signal, the equalising signal is reduced.

Title: Capacitor with pressure gas bearing for electrodes - uses gas bearing to define mutual electrodes position and guide elements mounting
Inventor: KLONZ MANFRED DIPL ING
IPC: H01G5/16
Filed: 1975-11-29
Abstract: The variable capacitor has metal electrodes whose mutual position, as well as the guide and adjustment elements, is determined by a pressure gas bearing. Each of the bearing is supplied from outside with pressurised gas via bores or slots leading into the respective bearing gap. The bearing body preferably consists of a porous, permeable material, permitting pressurised gas passage to the bearing gap. The bearing body may be alternately partly of porous and partly of non-permeable material. The electrodes spacing and thus the capacitance value can be changed by gas pressure variations. If nozzles are used for gas supply the variability can be obtained by changing their numbers.

Title: Electronic costume jewellery - has artistic part, containing assembled electronic elements producing optical signals on selected spots
Inventor: KUNDISCH HEINRICH
IPC: A44C15/00
Filed: 1975-12-17
Abstract: The jewellery consists fo a conventional artistically created part containing an assembly of electronic elements which produce optical signals on pre-selected spots or areas. The design makes the piece of jewellery visibly apparent even in the dark or half-light. This is achieved by fitting into the jewel one or several luminous diodes which are glowing in the dark, giving either a continuous or intermittent signal.

Title: Paper making sieve mesh cleaning system - has a catch trough with moving spray tube and scrapers to clear collected dirt from the trough
Inventor: HAMMELMANN PAUL
IPC: D21F1/32
Filed: 1976-07-17
Abstract: To clean a long mesh sieve, used in a paper making machine, a spray tube is moved forwards and backwards over the sieve to remove any dirt or debris. A catch trough is mounted with the spray tube in the area of the forced water sprays. This can be cleaned by a clearing tool moving along the length of the spray tube as far as the end of the trough, located above a catch vessel. The movement of the spray tube provides the power for the cleaning tool and ensures that the removed dirt is cleared so that there is no build-up which would require bringing the machine to rest for chemical cleaning. This is partic. the case when removing tar, adhesives, plastics or resins from a plastic sieve.
